The article explains Awin’s [Conversion Protection Initiative (CPI)](https://www.awin.com/gb/cpi) and how it ensures accurate conversion tracking. Tracking is the foundation of affiliate marketing. CPI addresses common challenges in affiliate tracking, such as: - Privacy regulations - The end of third-party cookies - Issues with ad blockers and browser restrictions Without accurate tracking, your sales may be under-reported, budgets misallocated, and affiliate commissions miscalculated, leading to potential revenue loss and damaged affiliate relationships. CPI ensures your affiliate program tracks conversions accurately and fairly. ## What’s required To be compliant, advertisers need to: - Upgrade to server-to-server (S2S) tracking. - Enable app tracking (if you have an app). If these updates aren’t made, Awin will use a probabilistic model to estimate the missing conversions. ## How does CPI affect you ### If you’ve upgraded your tracking - Your conversions are tracked accurately. - You get better insights and precise data. - You ensure correct commission payments to your partners. ### If you haven’t upgraded your tracking Awin’s probabilistic model will estimate your sales, resulting in: - 20% uplift for missing app tracking. - 12.6% uplift for missing S2S tracking. - Up to 32.6% increase in reported conversions to ensure accurate partner commission distribution. ## How to check if you’re compliant with CPI - **For S2S tracking** - Use Awin’s [Tracking Diagnosis Tool](https://awin.link/tracking-wizard-asc).
